Car Engine Making Loud Whirring Noise

Causes of a Loud Whirring Noise from the Car Engine

There are several possible causes of a loud whirring noise coming from your car engine. Some of the most common include:

Worn or damaged serpentine belt. The serpentine belt is a long, thin belt that drives multiple accessories in your car, including the alternator, power steering pump, and air conditioning compressor. When the belt becomes worn or damaged, it can start to slip and make a loud whirring noise.
Worn or damaged idler pulley. The idler pulley is a small pulley that helps to keep the serpentine belt in place. When the pulley becomes worn or damaged, it can start to make a loud whirring noise.
Worn or damaged tensioner pulley. The tensioner pulley is another pulley that helps to keep the serpentine belt in place. When the pulley becomes worn or damaged, it can start to make a loud whirring noise.
Worn or damaged water pump. The water pump circulates coolant throughout the engine to keep it cool. When the pump becomes worn or damaged, it can start to make a loud whirring noise.
Worn or damaged power steering pump. The power steering pump assists with steering the car. When the pump becomes worn or damaged, it can start to make a loud whirring noise.
Worn or damaged alternator. The alternator charges the battery and powers the electrical system in the car. When the alternator becomes worn or damaged, it can start to make a loud whirring noise.
